Stopping way down and shooting in the 70-100mm range seems to work just fine, but it's hard to believe this lens gets so much positive attention with it basically blowing up at 200mm 5.6. Is there a really wide range of optic quality on this?

Easily possible, especially with a zoom lens that might have passed through many hands over 25 years. One misalignment could cause poor performance only apparent within a certain aperture/focal length range.
